Hi Mauro,
The patch is against Greg's staging-testing branch. If you want it against any
of your branches let me know and I will fix it.

I just sent two patches. The first one changes the original patch to follow the
format you suggest here. The second one changes the rest of the driver to be
consisent with this.
Thanks a lot for the review :)
